Question 433806: 150x^2-96
Please help me factor....
I have four answers
1.(30x-24)(5x+4)
2.6(5x+4)^2
3.6(5x-4)(5x+4)
4.(5x-4)(30x+24)
i think 1 and 4 are the same,and they make sense because 1. 30x+5x=150x^2
but im not sure..

thanks
Paola

150x^2-96
=6(25x^2-16)
6((5x)^2-4^2) this is in the form of a^2-b^2=(a+b)(a-b)
=6(5x+4)(5x-4)ANS
1and 4 answers are not same 30x+5x=35x
